I don't know for sure, but I suspect that CRT TVs sold in PAL countries have shadow masks/phosphors optimized for ~576 scanlines.

They certainly are affected by the earth's magnetic field. We had to recalibrate all the magnetics in a bunch of broadcast monitors we brought in from the US.
A CRT from the Northern hemisphere is setup for the earth's magnetic field in that hemisphere, take it south and you get all sorts of colour problems. Same is true in reverse. You don't wanna import CRTs across the equator unless you know how to adjust them at the other end.
Back on topic the scaling on the PAL versions doesn't appear to be done very well, and some form of vblur has also been applied by the look of it. That is why I sent my PAL version back and got the NTSC version, I'd rather do any upscaling myself and get it as right as possible.
